Description
Technical Field
The utility model relates to a system for adopt among the metallurgical technology field to grab steel machine and add steel scrap to converter high efficiency.
Background
The scrap steel is used as a circulating renewable resource, and the recycling of the scrap steel has higher environmental protection, economic and social benefits. In iron and steel enterprises, the comprehensive energy consumption of iron making and pre-iron working procedures accounts for more than 60% of the energy consumption of iron and steel production, the steel scrap consumption of steel making is increased, and the comprehensive energy consumption in the iron and steel production process can be greatly reduced. Statistical data show that the consumption of 1.7t concentrate powder, 1.6t carbon emission, 1t raw coal consumption and 2.6t steel tailing slag emission can be reduced every 1t steel scrap is added.
Thirteen-five planning in China is proposed, and the steel-making scrap steel ratio is improved to 20% in 2020; the Ministry of industry and belief 2015, 12 months out of the work, proposed "policy adjustment plan for iron and steel industry", and the application proportion of scrap steel was increased to 30% by 2025. For steel plants, the converter scrap ratio is improved, the production efficiency of the converter can be improved, the production cost of raw materials is reduced, and the economic benefit of a company is increased. Therefore, it is a trend of the future steel industry to improve the scrap ratio from the national policy of administration or the self-operating benefit of the enterprise.
According to the statistical prediction of the steel scrap association, the total amount of steel scrap resources in the country in 2018 reaches 2.2 hundred million t, the estimated steel accumulation amount in China reaches 120 hundred million t in 2025, and the annual output amount of steel scrap exceeds 2.7-3.0 hundred million t; in 2030 years, the steel accumulation amount in China reaches 132 hundred million t, and the annual output of scrap steel exceeds 3.2-3.5 hundred million t. With the increase of steel accumulation and steel scrap resources and the prominent advantage of steel scrap price in China, the total amount of steel scrap resources in China will be quite sufficient in the next 20 years.
The conventional scrap supply manner of converter steel plants is outsourcing scrap (packaging scrap, large scrap, bulk scrap and the like) → scrap yard → scrap disposal (cutting, crushing, screening, sorting, removing nonmetal, nonferrous metal, radiation metal and the like) → converter steel plants use magnetic disc cranes to carry out scrap batching → crane lifting scrap tanks → converter blending.
In order to increase the charging amount of the scrap steel, most enterprises adopt the following methods to increase the charging amount of the scrap steel: (1) enlarging the volume of the scrap steel groove; (2) adopts a double-groove scrap steel feeding mode. However, the disadvantages of these two methods are as follows:
method (1): due to the limitation of the capacity of a crane for adding the scrap steel, the size of a converter mouth and the increase of light and thin scrap steel, the capacity of the enlarged scrap steel groove is limited, and the maximization is difficult to achieve. Method (2): the mode of feeding the double-groove scrap steel increases the consumption of the scrap steel, but prolongs the feeding time of the scrap steel of the converter, increases the period of the whole smelting process, reduces the production efficiency and is not paid.
